The binding, the frame member and the sheet of transparentmaterial are also preferably secured togetherby an adhesive such ascement which will work through the thread needle holes in the bindingandmake a solid uniform combination structure of binding, Celluloid andwire. The arrangement of the stitches very close to the wire form andthe cementing of 'the binding, the Celluloid and the wire form resultsin a firmer, tighter non-slipping form in the binder and provides astiff construction for reinforcing the transparent walls and for main nthe same in their true original shape, whether the receptacle iscylindrical or any non-circular or poly onal form.

Transparent walls 4 are fitted within and secured'to a bottomsectioncomprising an opaque bottom It of well seasoned cardboard or othersuitable material and an upstanding rim [5 of shrinkable material suchas single ply or laminated cardboard or analogous material such as woodveneer. The upstanding band l5 which is arranged exteriorly of thetransparent walls is secured to the peripheraledge of the bottom l4preferably by cement or other adhesive material and the bottom I4 andthe upstanding band or rim are covered with decorativepaper It or othersuitable material such as cloth. In the construction of the bottomsectionv the opaque bottom is die-cut to the desired shape and thematerial forming the rim or upstanding band is cut to exact length tofit snugly around the edge of the bottom. .The opaque bottom I is of adiameter slightly greater than the body and extends slightly beyond theouter face of the bottom binding l0, and this in conjunction with theouter portion of the binding Ill offsets the band l5 from the plane ofthe flexible transparent walls 4 of the body portion prior to theshrinking of the band on the body portion, and the upper edge of theouter portion of the lower binding It forms a shoulder exteriorly of thetransparent wall 4, so that when the band I5 is shrunk on the bodyportion the band will engage said shoulder of the lower binding In andinterlock the band with the body' portion of the container. The paper orveneer band is of such construction and consistency as to shrinkconsiderably when allowed to dry after being'wet. One edge of therimtaken to keep all measurements constant so that when the wire-formedside wall is inserted in the bottom section it will fit accurately andtightly against the wet side of the bottom, so that as the upstandingband ll starts to dry and to shrink it closes tightly around theinserted wire form. This shrinkage of the projecting portion of the rimagainst the transparent wall, in addition to securely clamping theopaque bottom to the wire bottom form so that no cement is reallyrequired to hold' the side wall firmly and securely in the bottomsection, also fills in and closes the space between the transparent sidewall and the inner face of the projecting portion of the upstanding rimmaking a smooth connection between the transparent wall and the bottomsection and materially enhancing the appearance of the container.

The wire for the transparent wall is cut to the exact length and formedto the desired shape before the ends of the wire are welded together andthe wire forms are always constant for each size of container. Inapplying the Celluloid or other transparent sheet to the forms or framemembers! and 8 one end and one edge of the transparent sheet is properlyarranged on one of the wire forms and the stitching of the binding tothe transparent sheet and wire form is commenced. This stitching iscontinued until the entire form has been covered and a suitable overlapof the binding stitched chat the point of closure. The necessary lap forjoining 0r cementing the seam andjolning the transparent side wall isthen in proper position for cementing. Itis necessary and desirabletolwait until the stitching has been applied to at least one edge beforecementing the overlapped edges of the sheet because the stitching closeto the wire form or peripheral frame member produces a constant tensionon the transparent sheeting. This is done to obtain a straight and trueshape without wrinkling the side wall when, stitched.

-mented. This method produces a taut, tight and true shape side wallwithout wrinkles or other imperfections whlch'would mark the appearance"and affect the saleability of the merchandise.

forming band is in contact with the edge of the bottom and consequentlyafter it has been wet with glue containing water it cannot shrinkbecause it cannot compress the stiff well-cured bottom piece 14.. Theportion of the upstanding rim above the bottom piece shrinksconsiderably and such shrinkage when complete produces a decided anddefinite .inward pitch to the upwardly projecting portion of the rimfrom the bottom piece to the top edge of the band and this shrinkage isutilized for interlocking the band with the upper edge of the outerportion of the lower binding ill and firmly and securely fastening thetransparent walls to the bottom of the container. Soon after the band iswet with glue and moisture in the assembly of the bottom section and theapplication of the decorative pap'er or other material and before thebottom section has started to shrink permanently or materially the wirereinforced side wall is inserted and at the same time glued with strongcement to the bottom and part way up the side wall. Care is The otherwire form or peripheral frame member is then stitched in a similarmannerand the seam or overlap of the ends of the transparent sheet isthen cemented together making a strong, tight and true form or shape ofthe Celluloid or other transparent sheeting.

If additional strength isdesired then a very strong combination ofbinding, thread, transparent side wall and wire peripheral frame memberis formed by applying cement with suitable solvents tothe' binding atthe point of stitching as heretofore explained... The cement whichenters the binding where it is perforated by the needle not only forms asolid bond between the transparent sheeting, thread and binding with thewire frame member but it also closes any rupture in the transparentsheeting where the same is pierced by the needle and thereby making thesheeting even stronger at this point than anywhere else in the sidewall.

The time required for maximum shrinking of the bottom band or rim l5varies with weather conditions and the type and quality of decorativecovering employed. Usually, however, shrinkage is practically completeat the end of 26 hours and the container is ready to ship.

The cover is made in "substantially the same manner as the bottomsection except that shrinkage of the side band or rim ll on the top.

wall or die-cut piece ll of opaque material is not necessary forconstruction purposes. The rim i1 and the opaque top wall I. are coveredwith suitable decorative material I! and the cover is designed to have aloose fit on the transparentside wall I,- but should it be desired topermanently secure the top wall to the transparent side wall the rim I!may be shrunk on the transparent side wall in the same manneras the rimof the botton section. The permanently attached top wall' or cover isdesignedto be employed where access to a container is provided at someother point ,and by some other means such as an opening in ripheralframe members of the form of the container, a sheet of thin flexibletransparent material impervious to liquid secured to theupper and lowerframe members to form a body por-' tion, and a bottomsection composed ofan opaque bottom and an upstanding rim having a definite inward pitchand shrunk on the lower end of the body portion, said body portion andrim having cooperating means for interlocking the rim withthe bodyportion.
